<4> 테스트 완료후 클러스터 삭제
<1> 기본 환경 설정
1
cloud shell 실행
2
gcloud auth list
승인
gcloud config list project
gcloud config set compute/zone us-central1-a
3
설정 확인
gcloud config list
<2> GKE 클러스터 생성
1
gcloud container clusters create [CLUSTER-NAME]
gcloud container clusters create blockgame-gcp-k8s
(3분 걸림)

kubectl get nodes

참고 사항
콘솔을 통해 클러스터를 만든경우
Kubectl api 사용 설정을 수동으로 해야만 kubectl 명령을 사용할 수 있습니다.
gcloud 명령어가 kubeconfig파일을 자동으로 업데이트 합니다.
gcloud container clusters get-credentials [CLUSTER-NAME]
gcloud container clusters get-credentials blockgame-gcp-k8s

<3> 모니터링과 배포
1
모니터링?
Cloud shell 하다더 띠우고 모니터링
watch -d kubectl get deploy,svc,pods
2
배포
kubectl create deployment block-server --image=gcr.io/google-samples/hello-app:1.0
3
로드밸런서 연결
kubectl expose deployment block-server --type=LoadBalancer --port 80

잘 된다!!
8080은 잘 된다.
<4> 테스트 완료후 클러스터 삭제
gcloud container clusters delete [CLUSTER-NAME]
gcloud container clusters delete blockgame-gcp-k8s
<엔터>
The following clusters will be deleted.
- [blockgame-gcp-k8s] in [us-central1-a]
Do you want to continue (Y/n)?
